SIGHT FOR FIREARMS.

Specification of Letters Patent.

Patented Jan. 11, 1916.

Application filed October 6, 1914. Serial No. 865,265.

Vnovel construction and arrangement of parts whereby there is produced a sighting device that at once is simple, reliable, compact and readily adjustable and may be attached to the barrel or other suitable part of a gun without adjunctive parts for keeping it in place.

In the accompanying drawing, Figure l' is a plan view of a gun barrel and my sighting device attached thereto; Fig. 2 is a view mainly in longitudinal section of what is shown in Fig. 1; Fig. 3 is a side elevation and underneath plan of the nut member of the means for effecting elevation adjustment; and, Figs. 4, 5 and 6 are respectively a longitudinal sectional view, an; end elevation, partly in section, and a view of a detail of the rear end of the sighting device illustrating particularly the windage adjustment means.

In said drawings, a is a gun barrel provided with a transverse dove-tailed groove adapted to receive, with a driven fit, the transverse dove-tailed tongue c of a blade d, said tonguev projecting from one flat side of the blade near one end thereof. Then the blade is attached to the barrel a by driving the tongue c into the groove b from one side, the adjoining part of the blade lies in face to face contact with the barrel; but preferably the remaining portion of the blade is elevated out of the plane of the part thereof having the tongue, as shown in Fig. 2, standing approximately parallel with the barrel.

Fitted into a rectangular hole ein the free or elevated portion of the blade is the rectangular reduced portion or stud f of a vertical screw g which is tapped into a diskshaped nut it having a milled periphery and preferably formed with a depending hub and in its under face with a series of regularly spaced recess j concentric with the screw g and giving the nut the function of a ratchet. For every recess j the nut on its upper face, which constitutes a dial, has a mark or index near the periphery, such marks being numbered 0, l, 2, 3, etc.

The barrel is formed with a circular recess /e to receive the nut 7a and with a coun` tei-sunk concentric bearing recess Z to receive the hub z'. In registry with the circular series of recesses j in the nut there is formed in the gun barrel a vertical hole m in which is set a pin n having its upper end preferably rounded and adapted to engage in the recesses y'.

The blade cl is elastic and since it overlies and bears on the screw-and-nut adjusting means, the parts thereof and pin n are kept in place by the blade, only such simple operations for adapting the sight to the barrel as forming in the barrel the groove b, recesses 7c Z and hole m being thus necessary.

In the present case, elevation adjustment being obviously accomplished by turning the nut, the operator determines the elevation obtained by reference to the numeral which at any time is at the extreme right of the nut (upper part thereof, Fig. l).

The free end of the blade Z is bent into substantially the form of a cylinder o on which slides transversely the split cylindrical portion p of the sight proper g, the same having a sighting point 7'. The part o of blade (Z is internally threaded and tapped into the same is a screw s having heads t and u, the latter of which may be removably held in place by the pin o. Between one of the heads, as t, and the sighting device g there is arranged a spring lw, in the present case being a dished metallic disk; the other head, as u, has a concentric series of regularly spaced recesses on the side thereof adjoining the sighting device, and in a suitable hole y in the latter registering with said series of holes is set a pin z. With the coaction of the spring w there is thus produced a ratchet connection as between the screw and the member g, whereby the parts will be held securely in any position, corresponding to any one of the recesses to which the screw is turned in adjusting the sight for windage.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is l. In combination, with a fLXed part of a y gun, a sighting device including an elastic blade arranged in atwise relation to and upon and secured to said part and having one end free and equipped with a sighting point, and a screw-and-nut elevating means for said efebladerremovablyrarranged on and countersunk in said part and overlapped and held in the countersink by said end of the blade.

2. In combination, with a fixed part of a gun, a sighting device including an elastic blade arranged in flatwise relation to and upon said part and having a tongue-andgroove connection therewith separable by movement of the blade laterally in substantially its own plane, and a yscrew-and-nut elevating means for the blade attached thereto and arranged between said blade and said tween them the other member, one head having a ratchet connection with said other member, and a spring interposed between the other head and said other member.

In testimony whereof I affix my signature in presence of two witnesses.
